Application filed February Thisinvention relates particularly to valvemechanism for'faucets and similar purposes. The object of the inventionis to provide such a faucet or similar structure with an effective anddurable valve mechanism adapt ed to seat automatically by water pressureand to be unseatedmanually.

In the accompanying drawings, Fig. l is a plan of a faucet structureembodying m-y improvement; L

Fig.2 is an upright section on the line, 2---2, of Fig. 1; I Fig. 3 is ahorizontal section on the line,

3-3, of Figs. 2 and 4;

Fig. 4: is an upright transverse section on the line, H, of Figs.'1,-2and 3, looking toward the left;

Fig. 5 is avtransverse section on the line, 5-5, of Figs. 2 and 3,looking toward the right;

'F'g. 6 is an upright transverse section, on the line, 6-6, of Figs. 2and 3, looking toward the right;

Fig. 7 is a side elevation of the forward valve member;

b Fig. 8 is a rear elevation of the same mem- Fig. 9 illustrates anotherform." Referring to said drawings, A is a valve pipe or tube, the rearend of which is to be threaded to a liquid delivery pipe (not shown). Bis the nozzle, the rear end of which is threaded around the forward endof the tube, A. A-washer, A rests on a shoulder, B formed on the nozzle,B, in front of the tube, A. An annular valve seat, A is placed againstthe washer, A at the rear side of the latter and is held in thatposition by engagement with the forward end of the tube, A.Approximately midway between the ends of the tube, A, is a centrallyapertured upright cross partition, A Against the rear face of thatpartition rests a metal ring-form valve seat, A, held by frictionalengagement of its periphery with the pipe.

A, and against which normally rests a ball valve, C, which is preferablyformed of metal.

The valve member. D, has a conical body, D which normally bears againstthe valve seat. A A stem, D extends forward from the body, D in positionto be engaged and pushed rearward by the cam to be described further on.From the body, D four arms. D extend rearward. On the outer face of eachsuch arm is a rib, D, which is parallel FAUCET.

tothe tube axis and bears loosely against the inner face ofthetube.These arms and ribs serve to hold the entire member, D, to movementparallel to the tube axis. On the axial line of the tube is a threadedstem, D which extends? rearward toward the ball, C. On said stem are apair of nuts, D, small enough to extend through the opening in thecrosspartition, A, and flll'lil'lfi, valve seat, A. These. nuts permitadjustment to vary the distance between them and theball, C, when saidball and the member, D, are seated. When the two :valves are to' beunseated to permit flow of liquid through the tube, A, the member, D, isto be pushed rearward until the stem, D either directly or throughthenuts, D, pushes the ba1l, O, rearward away from its seat. 1 i

The member, D, is pressed rearward by the turning of the cam, E. Thatcam is con trolled by the handle, F. The cam surrounds the four. sidedpart, F*, of the upright shaft, F on the upper end of which the handle,F, is immovably secured. Below the cam said shaft extends into abearing, B Above the cam the shaftrests in a bearing, B Abovethatbearing is a packing, member, B'f, threaded around said bearing.

.VVhen the cam is turned forward, as shown in Figs. 2' and 3, the valvemember, D, is free to seatin response to the forward pressure of-theliquid. When said member moves forward, the .stem,-'D moves away fromthe ball, O, and allows itito seat in response to the forward pressureof the liquid. The two valve members, the member, D, and the ball. C,remain thus seated until the handle, F, and the shaft, F are turned byan attendant to turn the cam, E, rearward into engagement with the stem,D of the valve member, D. whereby the entire valve member, D, is forcedrearward, whereby the stem, D is made to engage and push the ball, O,rearward away from its seat. Both valves are now unseated or open andliquid flows and continues to flow through the faucet until the cam, E,is again turned to bring it out of engagement with the stem, D of thevalve member, D, whereupon forward pressure of the liquid in the tube,A, presses both valve members against their seats. A stop. B is placedin the nozzle, B, in position to limit the movement of the cam. E,contra-clockwise as viewed in Fig. 3; and a stop. B", also formed in thenozzle, B, serves to limit the movement of the cam when it is movedclockwise as viewed in Fig. 3.

tionally to the washer, A instead of being i engaged between the washer,A and the tube, A. In the same figure, the ring-form valve seat A, A isused for Furthermore, the several parts are so proportioned as to causethe member, D, to hold the valve, 0, away from its seat when the member,D, is seated and the nozzle, B, is screwed into working position on thetube, A. Under this arrangement the valve,"O, seats only when thenozzle, B, is removed from the tube, A, whereby the washer, A and thevalve member, D, 'aremade free, the nozzle being removed for thepurposeof adjusting or repairing parts of the nozzle or themembe'ryl),or the seat,"A for that IIlGIIlbBL' In that case the seating of thevalve, 0, will prevent outward flow of water." By this means it is madeunnecessary to cut ofi the flow of water between this valve structureand the main pipe.

It will now be observed that all the parts of this faucet are made ofdurable material and are in form for strength and durability and all theparts are adapted to easy manufacturing and easy assembling anddismantling. No spring nor other parts which are subject to wear orderangement are used.

It will also be observed that this faucet will drain automatically whenthe main valve on a system of house water pipes is set for draining. Inthat case the forward pressure on the two valve members of my structureceases, and then those members are free to move away from their seatsand admit air, whereby the water behind those members is released forbackward or forward flow, according to whether the faucet is approachedby a pipe leading upward or downward.

When faucets donot thus release and drain other purpose.

I claim as my invention,

1. In a structure of the kind described, the combination ofrtwo valveseats directed toward the source of liquid flow, a cam for- Ward of theforward valve seat, means for turning the cam, a valve member at therear of the rear valve seat and adapted to seat thereon'by'forwardpressure ofliquid, a forvent freezing of water in the pipes or for anyward valve member adapted-to seat on the forward valve seat byforward'pressure of the liquid and extending through said seat into thepath of said-cam and said valve member having guiding arms and having'astem extending rearward and adapted to engage and dislodge the rearvalve member when the for- Ward valve member is pressed rearward by saidcam, substantially as described.

2. In a structure of the kind described,

the combination of two valve seats directed toward the source of liquidflow, a cam forward of the forward valve seat, means for turning thecam, a valve member at the rear of the rear valve seat and adapted toseat thereon by forward pressure of liquid, aforward valve memberadapted to seat on the forward valve seat by forward pressure of theliquid and extending through said seat into the path ofsaid cam and saidvalve member having an adjustable stem extending rear- 1' ward andadapted to engage and dislodge the rear valve member'when the forwardvalve member is pressed rearward by said cam, substantiallyas described.

In testimony whereof I have signed my name,'this 12th day of January, inthe year one thousand nine hundred and twenty-six.
